[Microsurgical anatomy of structures of the cerebellopontile angle in meningiomas of the posterior surface of the pyramid of the temporal bone].

The data of 153 operations and 38 autopsies were used to study the microtopographoanatomical relationships of structures of the cerebellopontile angle in meningiomas of the posterior surface of the pyramid of the temporal bone. The details of the microtopography of the structures of the cerebellopontile angle were studied on 6 block-specimens with meningiomas and during 20 operations by means of an operating microscope. The authors revealed variants of the relationship of the cerebellopontile angle structures with the tumors depending on the site and direction of their growth.
